| 摘 要： | 首先研究了地物光谱曲线特征点提取的方法,并列举了特征点的一些应用.然后根据实测的3个不同时期小麦的反射率曲线,在进行了均值去噪处理之后,设定振幅阀值,排除了残余噪音干扰,从而提取了曲线最重要的特征点.

| Abstract: | The paper is a research on the method of drawing out the characteristic points from a spectral curve and enumerating the applications of these points.The authors collected the spectral data of wheat in different occasions,got rid of the noises which happened in the course of measurationby ways of averaging near spectral data and ways of setting limiting figure to amplitude,thenthe most important characteristic pointsweregained. |
